[Q] My computer cannot recognize my devices MTP

I just got my Nexus 7(2013) device.
I used to transfer files between my computer and my Nexus 4.
When I plugged in my N4, my computer recognizes my N4 and device manager showed there is a portable devices "Nexus 4"
However when I plugged in my new N7, my computer cannot detect it and device manager showed "Android Device" with "Android Composite ADB Interface" under it.
I cannot find any new drive in My Computer although the device is charging through USB.
I have tried to disable/enable USB Debugging, using different USB cables, switching USB option between MTP and PTP and reinstalling Nexus usb driver from google and all of them do not work.
May I ask for any solution?
Thanks:fingers-crossed::fingers-crossed:

Uninstall/remove the drivers
reboot
then reinstall using these drivers

Even if you did it before, try again, with the removal of drivers and the reboot.
Also you may want to try different ports, cables, computers

I've tried that before
I may now try a few times more
By the way, I realized that I can use Wugfresh toolkit and completed the full driver test to bootloader mode. However, I cant even detect the hard drive.

I finally enabled to use PTP to access the photos.
However I am still unable to use MTP to transfer other types of files..
Any help?:fingers-crossed::fingers-crossed:

Please perform the following even if you have done it before.
In this current state, turn on MTP. Then turn off USB debugging. See if MTP shows up. If so, use this fix to get MTP working with USB debugging.

I am sorry that I cannot understand it completely.
May I ask
1. Should I uninstall just the entry with Nexus 7 as description in Nirsoft USBDeview and then reboot?
2. You mentioned that "When you turn on USB debugging and windows asks for an MTP driver, just provide mtp_driver.zip". How can I use the zip file? After rebooting and enabling USB debugging, my toolbar on bottom-right has a icon showing I have a MTP and I can choose to "remove MTP safely" just like plugging in a USB flash drive. However, there is not a hard drive in My Computer. Maybe is it the difference between Windows XP and WIndows 7? Or did I misunderstand your instruction?
Thanks for helping! :good:

I finally did it with USB debugging and MTP on.
I occasionally update the Android ADB Interface driver and install Composite USB Device from the list and my computer detects my hard drive!!
Is it possible to get my MTP working without enabling USB Debugging or is it normal to detect mtp with USB Debugging on? :good:

One of the drivers you installed previously which was modified to get MTP working. was implemented too aggressively and is now blocking your ability to use MTP with USB debugging turned off.
For normal systems with no drivers loaded, they have the opposite problem, in that they can get MTP working when USB debugging is disabled, but lose MTP when USB debugging is enabled.
When USB debugging is disabled and MTP is enabled, the USB port advertises that it is compatible with standard MTP drivers, so windows automatically installs. However if you have a custom driver installed, it can block that automatic process.
With USB debugging turned on, the USB port no longer advertises MTP compatibility, so windows is normally confused and doesn't know what driver to use. That you were able to get it working with USB debugging enabled proves to me that you have a custom driver installed that was modified to get MTP working.
The way I wrote my changes to the MTP driver was to leave the standard MTP alone and only intercept the MTP when USB debugging is enabled. Thus my changes don't block normal MTP operation when USB debugging is disabled.

Yes, but you are going to need to figure out which driver you installed is causing the issue and remove it so it doesn't get in the way.
Alternatively, try a different PC that has never had drivers installed and use just the one I pointed you at earlier.
You don't use the zip file directly, you unzip the contents and will have a .inf file.
When windows asks for a driver (USB debugging turned on and MTP turned on) you point the install at the .inf provided. It will do the rest automatically.

I have been using the same computer to root Galaxy Nexus and Nexus 4 and I remembered I have been using some tool similar to the one you provided.
Maybe it makes my computer cannot recognize the MTP
Anyway, Thanks

Zenfone 2 found through ADB but not in My Computer or Disk Management...

Zenfone 2 ZE551ML, rooted with 1-Click Root method, stock everything else, nothing touched, Developer Mode and USB Debugging on.
Here's what it shows when the device is plugged in. I have Intel Android USB Drivers installed. I have tried uninstalling the drivers through Device Manager, but the same driver keeps getting reinstalled.
MTP Mode is selected under USB Settings/Storage whatever it's called, so it should show up in My Computer but it doesn't.
Thanks!
EDIT: I think I solved it, just have to disable USB Development, unplug then replug with MTP or PTP enabled.

Solved: Usb debugging enabled- no ADB

Got an unlocked Tmo Note III, rooted.
Was trying to use adb, but my only usb options are Media Device or Camera.
No "just charging".
USB debugging is enabled, but doesn't show when I connect the phone to pc.
Any ideas what I'm missing here?
Edited to add:
Had to reinstall the Samsung drivers, and redo debugging privileges for pc

Cannot get ze551 to detect in Windows, tried everything

Friends,
I've searched through all the threads here and on zentalk but still no good.
I have a ze551 with Superzen, phone works fine however I cannot get it to detect in Windows.
Nothing shows up in device manager, I've tried USB Debugging, MTP and PTP. I've tried 3 different computers (2 x W10 and 1 x W7) and still no good.
The only detection I manage to get is a split second of MOOREFIELD showing up when powering the phone on.
I want to flash MM but cannot adb sideload due to this USB detection issue, any ideas?

What drivers did you install? When I first connected the phone to a pc I installed the Asus drivers but nothing worked. Everything began to work after installing the Intel drivers

try to revoke all usb debugging authorizations from developer options. then disable usb debugging and disable developer option and enable again. now enable usb debugging again. now connect to computer. now run command "adb devices" and authorize from phone.if u still have issue try changing usb cable.

I've tried the Intel drivers., the problem is the phone doesn't even get detected by windows, there's nothing showing up in device manager.
I do however get charging from USB.
I've tried USB 2.0 and 3.0 ports in 3 different computers, no detection.
It used to work fine, now it has just stopped working. Maybe the USB chip is fried or something.

may or may not. may be usb cable broke down data wire, may be connector issue. have you tried above said tips?

Hey,
I got the same problem, and the quick charging takes 7 hours or so, but I should mention previously that in my case the USB port was damaged, so I changed the whole dock. After change tried all other cables including the Asus official cable, still no joy. It looks like some updates made a big fuss in the phone or ... the motherboard is burnt? I tried on different computers with and without Android Intel USB drivers installed, but the problem is the computer cannot see the phone - I'm getting the message that the phone is not sending its designator. I have not rooted my zennfone, but when I try adb to see if the phone is mounted it's not. I was planing to root it now, but it looks like I cannot do anything. I'm affraid that there is something wrong with the hardware. I did started also SMMI test and it loops testing bluetooth, so definitely there is something wrong, but yet I have not figured out.

I have tried all drivers, the phone was working fine on my windows install and suddenly stopped.
I believe this is not a driver issue, it is hardware issue with the port or with the rom (superzen).
I will try to flash other rom as I have custom recovery and see if it fixes otherwise the port is busted.

ADB Debugging No Longer Connecting to PC

I'm stumped with this one. My HTC 10 no longer will connect to my computer at home or at work when I have USB debugging enabled. I don't get any entry in device manager. I'm running the 2.28.617.8 firmware w/ Viper 4.3.1. I utilize the universal adb driver. When debugging is enabled, the phone message says I'm connected to a slow charger. I have verified the ports on both computers are functional by attaching other devices. I have the connection settings for MTP enabled. I also tried revoking the debugging authorizations in the hope it would reset everything. The only way I can find around it, is to turn off usb debugging. Then, when I connect the phone it will mount properly and I can transfer files. This is ok for the short term, but is not ideal. Does anyone know what I might be missing?

I had this same issue after restoring a TWRP backup on a replacement 2.28.617.8 phone. RUU and restore all my settings mostly by hand fixed it.

Do you have HTC Sync installed? Try installing that, connect the phone and on the phone grant HTC Sync permission.
